Slow relaxation of magnetization and luminescence properties of a novel dysprosium and pyrene-1,3,6,8-tetrasulfonate based MOF

Abstract

We report the formation of a novel multifunctional metal–organic framework (MOF) based on dysprosium(III) ions using pyrene-1,3,6,8-tetrasulfonate (pytet)⁴⁻ as a ligand, synthesized using a soft hydrothermal route. This material shows a two-dimensional network with small channels along a crystallographic axis and displays intense photoluminescence properties in the solid state at room temperature due to the pyrene derivative ligand. The magnetic properties of this 2D-MOF are also accomplished, confirming slightly frequency-dependent out of phase signals under an applied field of 1000 Oe.
